A patient has been living with seasonal allergies for many years, but does not take antihistamines, stating, "When I was young I used to take antihistamines, but they always put me to sleep." How should the nurse best respond?
A) "Newer antihistamines are combined with a stimulant that offsets drowsiness."
B) "Most people find that they develop a tolerance to sedation after a few months."
C) "The newer antihistamines are different than in years past, and cause less sedation."
D) "Have you considered taking them at bedtime instead of in the morning?"
Ans: C
Feedback:
Unlike first-generation H1 receptor antagonists, newer antihistamines bind to peripheral rather than central nervous system H1 receptors, causing less sedation, if at all. Tolerance to sedation did not usually occur with first-generation drugs and newer antihistamines are not combined with a stimulant.
